  Synthesis and antiviral activities of hexadecyloxypropyl prodrugs of acyclic nucleoside phosphonates containing guanine or hypoxanthine and a (S)-HPMP or PEE acyclic moiety

  摘要：

  Hexadecyloxypropyl esters of acyclic nucleoside phosphonates containing guanine (G) or hypoxanthine (Hx) and a (S)-[3-hydroxy-2-(phosphonomethoxy)propyl] [(S)-HPMP] or 2-(2-phosphonoethoxy)ethyl (PEE) acyclic moiety have been prepared. The activity of the prodrugs was evaluated in vitro against different virus families. Whereas ester derivatives of PEEHx and (S)-HPMPHx were antivirally inactive, monoesters of PEEG, and mono- and diesters of (S)-HPMPG showed pronounced antiviral activity against vaccinia virus and/or herpesviruses. Monoesters of (S)-HPMPG emerged as the most potent and selective derivatives against these DNA viruses. None of the compounds were inhibitory against RNA viruses and retroviruses.

  The invention deals with the method of the synthesis of dialkyl haloalkylphosphonates and dialkyl haloalkyloxyalkylphosphonates via a microwave-heated Michaelis-Arbuzov reaction of trialkylphosphites with dihaloalkanes or bis(haloalkyl)ethers in a closed vessel, during which the reaction mixture, containing a dihaloalkane or bis(haloalkyl)ether and a trialkylphosphite, is heated with microwave radiation with the standard frequency (2.45 GHz) to reach a reaction temperature which is specific for each individual halogen. In the subsequent reaction of the first dihaloalkane or bis(haloalkyl)ether halogen atom with trialkyl phosphite, the desired dialkyl haloalkylphosphonate or dialkyl haloalkyloxyalkylphosphonate is formed, but the reaction of its halogen atom with the so-far present trialkylphosphite, leading to the creation of the relevant bisphosphonate, no longer takes place. In the case of an inhomogeneous reaction mixture, also the desired product in the amount of 0.1-5 molar % is added to the reaction mixture for its homogenization, which homogenizes it and thus precludes its uncontrollable overheating. The entire process of synthesis is more effective, faster, less expensive and more environmentally friendly than the methods described so far in the literature. The possibility of performing the described procedure also in a continuous-flow microwave reactor allows industrial production with minimal demands on an optimization of the reaction conditions for larger quantities, eliminates some security risks, dramatically reduces the spatial demands in production and reduces the need for the usage of large-tonnage industrial reactors.

  该发明涉及通过微波加热的Michaelis-Arbuzov反应，在封闭容器中合成二烷基卤代烷基膦酸酯和二烷基卤代烷氧基烷基膦酸酯的方法。在反应过程中，包含二烷基卤代烷基膦酸酯和三烷基膦酸酯的反应混合物通过微波辐射加热至标准频率（2.45 GHz）的反应温度，该温度对于每种卤素都是特定的。在第一个二烷基卤代烷基膦酸酯或二烷基卤代烷氧基烷基膦酸酯的卤原子与三烷基膦酸酯的反应中，形成所需的二烷基卤代烷基膦酸酯或二烷基卤代烷氧基烷基膦酸酯，但其卤原子与迄今为止存在的三烷基膦酸酯的反应，导致相关双膦酸酯的生成，不再发生。在反应混合物不均匀的情况下，还向反应混合物中添加所需产品的0.1-5摩尔%的量以使其均匀化，从而防止其不受控制地过热。整个合成过程比文献中迄今描述的方法更有效、更快、更经济、更环保。在连续流动微波反应器中执行所述程序的可能性使得工业生产具有最小的反应条件优化要求，消除了一些安全风险，显著减少了生产中的空间需求，并减少了对大吨位工业反应器的使用需求。
• Aza-acyclic Nucleoside Phosphonates Containing a Second Phosphonate Group As Inhibitors of the Human, <i>Plasmodium falciparum</i> and <i>vivax</i> 6-Oxopurine Phosphoribosyltransferases and Their Prodrugs As Antimalarial Agents

  Hypoxanthineguanine[xanthine] phosphoribosyltransferase (HG[X]PRT) is considered an important target for antimalarial chemotherapy as it is the only pathway for the synthesis of the purine nucleoside monophosphates required for DNA/RNA production. Thus, inhibition of this enzyme should result in cessation of replication. The aza-acyclic nucleoside phosphonates (aza-ANPs) are good inhibitors of Plasmodium falciparum HGXPRT (PfHGXPRT), with K-i values as low as 0.08 and 0.01 mu M for Plasmodium vivax HGPRT (PvHGPRT). Prodrugs of these aza-ANPs exhibit antimalarial activity against Pf lines with IC50 values (0.8-6.0 mu M) and have low cytotoxicity against human cells. Crystal structures of six of these compounds in complex with human HGPRT have been determined. These suggest that the different affinities of these aza-ANPs could be due to the flexibility of the loops surrounding the active site as well as the flexibility of the inhibitors, allowing them to adapt to fit into three binding pockets of the enzyme(s).

  This paper deals with a novel, efficient and environmentally friendly synthesis of dialkyl haloalkylphosphonates via a microwave-assisted Michaelis–Arbuzov reaction. The approach is solventless, requires only one equivalent of each of the starting compounds, and provides high yields of pure products from which the impurities are easy to remove. The process has been optimised for batch and flow reactors
